This report describes the tests and results of a model study conducted at the Mead Hydraulic Laboratory of the Kansas City Reach and the Kansas River Bend of the Missouri River. The study was performed by personnel of the Hydro-Sediment Section of the Omaha District, Corps of Engineers, under the general supervision of the Kansas City District and the Missouri River Division. Attempts to improve and control the Missouri River have been in progress for many years. Dikes, sills, and revetments of various arrangements have been constructed to control the overall river alignment and to insure a river channel of adequate depth and width to permit navigation. The channel alignment of the Missouri River between Sioux City, Iowa and its mouth at St. Louis, Missouri, has in general been established with the shape of each major bend controlled by a combination of spur dikes and bank revetments. However, many times problems still appear within this general alignment. Maintaining an adequate navigation channel through the Kansas City Reach and the Kansas River Bend is a typical problem.
